This dataset contains absolute-gravity data collected by the USGS Southwest Gravity Program, a collaborative effort of the Arizona, California, and New Mexico Water Science Centers to monitor and model groundwater-storage change. Data were collected following the methods in "Procedures for Field Data Collection, Processing, Quality Assurance and Quality Control, and Archiving of Relative and Absolute-Gravity Surveys", U.S. Geological Survey Techniques and Methods book 2, chapter D4 (https://pubs.er.usgs.gov/publication/tm2D4). All data are reviewed and approved. Additional data, including network-adjusted relative- and absolute-gravity data, may be available in ScienceBase Data Releases (https://www.sciencebase.gov/catalog/item/5910bebae4b0e541a03ac8f8).
